When using a dropdown component, you will need to add a specific dataset (in the bottom right-hand modal) for your dropdown.
If you use the same dataset for your dropdown and to power your charts, when you select an option from the dropdown and pass that variable as a filter on the dataset, the dataset will be filtered everywhere it’s used - including in your dropdown!
We suggest adding a specific dataset called ‘dropdown dataset’ or ‘unfiltered dataset’ for your dropdowns.
